The deep application of sun workstation in Network

At present, the application system based on client/server (c/s) network architecture is more and more mature. The UNIX operating system with multi-user Multitask network has become the main operating system on the background server of C/s structure system with its high reliability, high scalability and high opening characteristics. The SOLARIS2 of sun Company is used in the system we develop. 5. 1 operating system, it has a very powerful network function, in order to fully play its role, we not only let it assume the core work of the database system, but also to become the system of PPP dial-in server, soft routing server or NFS shared disk server. Here are some of my experiences in using.

Set Solaris to PPP dial-in server

Since we have developed a system to be installed in the field, we will set Solaris into a PPP dial-in server, and then through the remote dial-up Internet, on the basis of PPP using the TCP/IP protocol to remote logins or transfer files, to our maintenance work with great convenience. The following are the setup steps:

First, set up the modem:

1, with the modem with the series cable connected to the modem and Sun Workstation serial port A (or B, the following serial port A as an example), open the modem power switch.

2, edit the file/etc/remote, add the following:

#vi/etc/remote Edit File/etc/remote

cuaa:dv=/dev/cua/a:at=hayes:br#38400 hypothesis with a serial port

3, set up the modem, on the command line issued the following command:

#tipcuaa;tip is the Connect remote system command

[connected]; Indicates that the modem is connected to normal

Ats0=1; set to Automatic response mode

Ok;modem successful execution of return information

at&c1; set to trace data carrier

Ok

at&w; Storage Settings

Ok

~ ; Exit Tip Command

[EOT]

#; Returns to the command line state

After the completion of the above steps, the modem will have HS, AA, TR, Mr Four led light (take the Hayesa series as an example).

Second, set up the Sun workstation serial port:
